-        The phenomena of prokaryotic restriction and modification, as well as anti-restriction, were first discovered five decades ago but have yielded only gradually to rigorous analysis. Work presented at the 5th New England Biolabs Meeting on Restriction-Modification (available on REBASE, http://www.rebase.com) and several recently published genetic, biochemical and biophysical analyses indicate that these fields continue to contribute significantly to basic science. Recently, there have been several studies that have shed light on the still developing field of restriction-modification and on the newly re-emerging field of anti-restriction.

-*"Bacterial restriction-modification (R-M) systems function as prokaryotic immune systems that attack foreign DNA entering the cell :ref{doi=10.1128/jb.65.2.113-121.1953}. Typically, R-M systems have enzymes responsible for two opposing activities: a restriction endonuclease (REase) that recognizes a specific DNA sequence for cleavage and a cognate methyltransferase (MTase) that confers protection from cleavage by methylation of adenine or cytosine bases within the same recognition sequence. REases recognize ‘non-self’ DNA (Figure 1), such as that of phage and plasmids, by its lack of characteristic modification within specific recognition sites :ref{doi=10.1093/nar/29.18.3705}. Foreign DNA is then inactivated by endonucleolytic cleavage. Generally, methylation of a specific cytosine or adenine within the recognition sequence confers protection from restriction. Host DNA is normally methylated by the MTase following replication, whereas invading non-self DNA is not."*
